Objects must cease, mind must become just a pure mirror - a mirroring, not mirroring anything - just a mirror without any object in it, a pure mirror. By dhyan, this purity of the mind is indicated. So first, no object should be in the mind. Mind must remain alone without thinking about anything - with no thought, just a consciousness, just an awareness, just an alertness. This alertness without any object is meditation. - Rajneesh
